Most remote job listings say "work from anywhere." Almost none of them mean it.
Dig into the fine print and you find the real requirement: overlap hours. Most remote roles want two to four hours of daily crossover with the core team. Sales, support and customer success roles often want four to six. Engineering and product teams can usually survive on two or three, enough for a standup and a decision or two.
Phuket sits at GMT+7, which makes this either a gift or a problem depending on where your employer sleeps. Australia and Singapore are easy. Europe works if you accept that your afternoons belong to other people, since a London team's morning is your late afternoon. US East Coast is where it gets ugly. Their 9am is your 8pm, and their full workday eats your entire evening.
Our members in Phuket run into this constantly, usually after they have already signed the contract. The fix is boring but it works: negotiate the overlap window before you accept, not three months in. Ask how many hours of crossover they actually need and which hours specifically. Then say yes or say no with your eyes open.
The other half of this is writing things down. Teams that survive across timezones do it with handoff documentation, not heroics. A clear written summary at the end of your day lets someone else pick the work up while you sleep. That is the whole trick, and it is a skill worth getting good at.
Harvard Business School found that 43% of real-time work conversations happen when at least one person is outside their local working hours. Someone always pays for the gap. Decide in advance whether it is going to be you.
